Detailed Introduction

KEJBY-A Single-phase Relay Protection Tester

I. Product Overview:
The KEJBY-A single-phase relay protection tester is a highly intelligent, multifunctional relay protection calibration device developed by our company based on the original product.
The KEJBY-A single-phase relay protection tester adopts microcomputer technology and is composed of a microcontroller, logic control unit, AC/DC current and voltage output unit, high-precision data acquisition unit, LCD display, real-time clock, printer, etc. It has high measurement accuracy and good repeatability. The instrument also has the advantages of beautiful appearance, reliable performance, simple operation, and complete functions, making it an ideal testing device for calibrating relay protection devices.
The KEJBY-A single-phase relay protection tester can test various AC/DC current, voltage, intermediate signal and other individual relays, as well as complete relay protection panels. It can test the pickup voltage (current) value, release voltage (current) value of various relays, and the pickup time and release time of various contacts (normally open, normally closed, changeover, time-delay). It automatically tests three times, calculates the average of the three times, and can print the test results.

II. Main Features:
Since this machine adopts microcomputer control, it provides Chinese character prompts for operation. The machine also has a self-check error reporting function. After power-on, the machine immediately performs self-check, which greatly facilitates inspection and maintenance. Such as "pickup voltage", "release voltage", "normally open pickup time", etc.
